Access pixels (I need for speed!)
Posted on 2004-04-23
I want to get about 500 squares with different size from a bitmap and stretch them into 40 x 40 squares. these lines are to slow to do it:
to make 500 of strbitmaps it takes more than a second. how can I make it faster. and also I want to access pixels faster - for example I want to count pixels with redvalue of 200~255. don't tell ScanLine is fast ;)
If DirectX or OpenGL are to solve it, please name some good packages which do that.
